PURPOSE: The usefulness of transcranial Doppler monitoring in identifying emboli in the arterial circulation has been established. We attempted to extend this technique to identify embolism in the venous circulation and to note any changes in embolism rate with anticoagulation. METHODS: From March to July 1993, 218 patients were evaluated by duplex scan for deep venous thrombosis. RESULTS: Sixty patients had positive study results; 26 scans (43%) demonstrated embolism. In five patients (19%) the emboli were also seen on a B-mode image, enabling us to estimate embolus size, which ranged from 200 to 5000 micrometer. Embolus counts varied from 5 to 800 per minute. Deep venous thrombosis was located in the iliofemoral vein in 2 patients, superficial femoral/profunda vein in 8, saphenofemoraal junction in 1, popliteal vein in 1, and the calf in 10. Concomitantly, studies in 158 patients were negative for deep venous thrombosis; embolism was detected in 4 patients (3%) in this group. In patients taking heparin, the embolus counts decreased 50% or more within 24 hours, and all embolism was abolished within 72 hours. Two patients died of pulmonary embolus. CONCLUSIONS: Patients with duplex scans that are positive for deep venous thrombosis have a high incidence of ongoing embolism. Heparin appears effective in eliminating the microemboli detected. The relationship among microembolism, deep venous thrombosis, and clinically significant pulmonary embolism remains to be elucidated.
Selected patients with primary varicose vein disease and sapheno-femoral reflux as the only point of regurgitation in the affected lower limb and duplex evidence of mobile valve leaflets underwent external valvuloplasty of the sapheno-femoral junction. Operations were performed under local anesthesia in one day-surgery. One PTFE sleeve 0.4 mm thick, in average 1.2 cm long and able to uncircle a circumference in average of 1.7 cm was put around the terminal Long Saphenous vein valve, located in the last centimeter of this vein. If also the subterminal Long Saphenous Vein valve site, located 5 cm below is dilated a second valvuloplasty was performed. In 15 case we used intra-operatory video-angioscopy guide. This examination allowed us to exclude two patients with valve damages not duplex demonstrable. Furthermore angioscopy permitted immediate demonstration of restored valvular function. Follow-up lasted on average 48 months: two early postoperative long saphenous vein thrombosis, and two late sapheno-femoral reflux recurrences were the main complications. We never observed graft infection. AVP was reduced and RT, measured by the means of LRR, had a prolongation after surgery. Both measurements had an highly significant difference from a statistical point of view, comparing pre and postoperative values. 95% of the operated patients have stable varices reduction. Long Saphenous Vein patency was recorded in 37 cases (92.5%). On the contrary, after high ligation, the fate of the saphenous vein in 21% of case is the occlusion. Symptoms of venous insufficiency disappeared completely in 80% of cases and improved in 95% of the operated patients.(ABSTRACT TRUNCATED AT 250 WORDS)
